SPRING FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 454,714, dated June 23, 1891.

Application filed April 4, 1891.

To all whom, it may concern.-

Beit known that I, GEORGE E. OoMBs, a citi- Zen of theUnited States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Iniprovements in Springs for Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to springs for vehicles; and it consists in certain improvements in the construction of the same, as hereinafter described and claimed.

In the accompanying drawings, Figure l represents a vertical longitudinal section of a wagon provided with my improvements. Fig. 2 is a plan of the Wagon inverted. Fig. 3 is a plan of the wagon-seat inverted.

A designates the wagon-box, B the front axle, and C the rear axle. The hounds a and the reach b are connected with the front axle in the usual manner. A bar c is secured by the king-bolt at the center in position over the axlehB.

D indicates two side bars, the forward ends of which rest on and are secured to the bar c, the rear ends of said side bars resting on the rear axle, to which they are secured. rIwo shafts d are centrally mounted under the wagon-box, and are journaled in the side bars D or in bearings carried by said bars. On each shaft d, nearits extremities, are mounted two pinions e, the said pinions being fast on the shafts, and so placed that the two pinions on one of the shafts d connectwith the` two pinions on the other shaft, as shown. Two

arms g extend from the more forward shaft d, and are pivotally connected with the bottom of the wagon-box near the front, the rear ends of said arms being rigidly attached to the shaft. Two similar arms g extend rearward from the other shaft d, being rigidlyv attached to said shaft, and having their rear ends loosely connected with the bottom of the wagon-box near its rear end. The connection of arms g with the wagon-box is formed of elongated'loops h, fastened to said box, and fixed pins extending laterally from said arms into said loop. The two sets of arms g g are provided with cross-bars m,

.a spring connected with and Serial No. 387,620. (No model.)

and a spring 'n is connected with said cross bars and retains the arms in positions inclining upward, as seen in Fig. 1. As will be seen, the rear arms g have a limited movement against the wagon-box at their rear A ends, the pins o moving in the loops h.

As the loaded wagon passes over uneven surfaces the outer ends of the arms g g are pressed downward by the weight of the load and are raised again by the spring n. The pinions e on one shaft CZ, engaging with the pinions on the opposite shaft, serve to equalize the pressure of the load, so that the wagonbox keeps its level position when the pressure is greatest, either in the front or rear part of the wagon.

The operative devices described may be applied to the seat of the vehicle.

E designates the seat, provided with the front and rear legs it', which answer the purpose of the arms g g. The two parallel shafts d are in this construction journaledin xed bearings fastened to the seat at its extremities. The bent legs c' z" are rigidly attached to the shaft d, the forward legs being removably connected with the wagon-box, and the rear legs resting on said box and having a movement thereon. Two pinions c are made fast to shafts d, in position to connect with each other, and one or more springs n are connected with the cross-rods m of the front and rear legs. As the seat is depressed as the wagon passes over uneven surfaces, the front and rear legs are spread somewhat, the legs c" sliding rearward on the surface 011 which they rest, but the latter are retracted by the action of the spring I claim-m l. The combination, with the body and the front and rear axles of bars carried by said axles,two parallel rotative shafts journaled in sad side bars and provided With pinions in pdsition to connect and engage said shafts, two arms extending forward from one of said shafts and connected with the body of the vehicle, two arms'extending rearward from the opposite shaft and loosely connected with the chicle-body, and adapted to raise said front and rear arms simultaneously, substantiallyas and for the prirpose described.

2. The combination, with two parallel roa vehicle, of two side IOO tative shafts provided With fixed bearings, of tending from one of the shafts d and contwo or more pinions secured to said shafts in nected with the vvehicle-body, arms g', expositions to connect one with another, oppotending rearward from the other shaft d, and 15 'site arms fixed to said shafts and extending in a retracting spring connected with arms g g',

5 opposite directions, and a retracting spring substantially as set forth and described.
